Invention field

The present invention is a kind of article, for example, by the clothes of dressing with it under wearer, as trousers or diaper.These article are designed to good fitness is provided and allow easily to introduce the element for improvement of the skin clean degree of wearer.

Background

People constantly seek to improve by the article (as trousers or diaper) of dressing with it under wearer about them in wearer fitness with it.In the past few years, concentrated on by improving the elasticity of the material that wherein adopted and made such improvement.In nearest method, introduced shank hoop, thereby lasting fitness next to the skin is provided, described at WO06/102974A1 (C4S).Although these designs and their manufacture (as described in WO08/141756 or WO2010/057543) are quite simple, for even more simply designing and exist needs.

Except simple and suitable design, due to article are considered to a long-term problem as insufficient processing of the excretion exudate in disposable absorbent article and analog to the pollution of wearer skin, but although very many solutions have been proposed, on market, there is no embodiment large-scale and that play a role at present.

Except above-mentioned patent publication, in US-5269775 (P & G), disclosed another kind of exemplary method, show that a top layer is used in disposable absorbent article, these article are divided into the trisection with different elastic characteristics.This top layer can further have one for EM is passed into the perforate of the void space in this disposable absorbent article by this top layer.

EP1279388A1 (P & G) described multiple absorbent commodity, wherein designed cuff (cuff) and provides a kind of for example for the barrier functionality of Excreta (more insensitive for the sedimentation after loading).

US-5462541 (K-C) has described a kind of absorbent commodity, these article comprise a top layer, a backing layer, an absorbent cores and a lifting device, and this lifting device forms a kind of shape of pocket-like for the top layer above this absorbent cores is mentioned.This top layer can have an opening and this absorbent can have a hole therein, and the two all receives and the separated refuse from wearer.

WO 09/119376A1 (Uni-Charm) has disclosed a kind of diaper, and this diaper has a sept and a separator, its objective is that the skin reducing in reproduction outside and perineal region is by manure contamination.

WO08/138018A1 (DSG) has disclosed a kind of article, and these article have top layer and the impermeable backing layer of liquid of an absorbent cores, a fluid permeable.Pair of flexible elastic cord lower limb enclose (leg wrap) from and along the edge of this core, stretch out, and comprise a series of isolated elastic cord rope strands.These lower limbs enclose and this core has formed one for trapping the storage of bodily exudate.In the use procedure of these article, these rope strands define one group of fluid interceptor, the liquid wastes that wherein each fluid interceptor has been caught certain volume make it not these lower limbs enclose and wearer between pass.

The ultimate principle of all these methods is to provide a kind of barrier material, once for after Excreta deposition just by it as much as possible with the skin of wearer and/or separate with genitals.For this reason, this barrier material expection is positioned near the anus of wearer, but in forms such as secondary top layer or separation barriers.Yet, it is believed that, the key reason that lacks the market introduction of functional product is in use often to maintain the registration between these Excreta separating devices and anus.As long as this registration is complete, this separation can be worked, if there is misalignment, if in the situation that there is no incident of leakage, in fact this may not cause than not having such separating device to compare more serious skin contamination far away.It is also believed that, the article with so conventional Excreta separation feature may more be difficult to application.

First solution of this problem is described in the applicant Concepts for Success (Success Concept Company) co-pending patent application (GB2475575) under one's name.Wherein, the registration of anus and separating device (as the form in secondary top layer) is by product being fixed and being realized around the both legs of wearer with shank hoop.

Yet, still needing a solution, this solution does not rely on the other feature of shank hoop, but therefore excremental separation is provided and has been easy to application by very simple mode.
